Package groovy.json

## Enum JsonTokenType

- java.lang.Object
- - java.lang.Enum<JsonTokenType>
  - - groovy.json.JsonTokenType

- All Implemented Interfaces:
    `Serializable`, `Comparable<JsonTokenType>`

      public enum JsonTokenType
      extends Enum<JsonTokenType>

  The original slurper and lexer use this class. This is kept around in case someone needs its exact behavior. Enum listing all the possible JSON tokens that should be recognized by the lexer.
  Since:
    1.8.0

    - #### OPEN_CURLY

          public static final JsonTokenType OPEN_CURLY

    - #### CLOSE_CURLY

          public static final JsonTokenType CLOSE_CURLY

    - #### OPEN_BRACKET

          public static final JsonTokenType OPEN_BRACKET

    - #### CLOSE_BRACKET

          public static final JsonTokenType CLOSE_BRACKET

    - #### COLON

          public static final JsonTokenType COLON

    - #### COMMA

          public static final JsonTokenType COMMA

    - #### NULL

          public static final JsonTokenType NULL

    - #### TRUE

          public static final JsonTokenType TRUE

    - #### FALSE

          public static final JsonTokenType FALSE

    - #### NUMBER

          public static final JsonTokenType NUMBER

    - #### STRING

          public static final JsonTokenType STRING

      Original pattern throws the StackOverflowError for long strings with backslashes. So it is replaced by a 2-step approach inspired from json2.js sources: https://github.com/douglascrockford/JSON-js/blob/master/json2.js#L462 See JsonTokenTypeTest#testMatchingLongStringWithBackslashes() for details.

  - ### Method Detail

    - #### values

          public static JsonTokenType[] values()

      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

          for (JsonTokenType c : JsonTokenType.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static JsonTokenType valueOf​(String name)

      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
        `name` - the name of the enum constant to be returned.
      Returns:
        the enum constant with the specified name
      Throws:
        `IllegalArgumentException` - if this enum type has no constant with the specified name
        `NullPointerException` - if the argument is null

    - #### matching

          public boolean matching​(String input)

      Tells if an input string matches a token.
      Parameters:
        `input` - the input string to match
      Returns:
        a `Matching` enum value: `YES` if this is an exact match, `POSSIBLE` if more characters could turn the input string into a valid token, or `NO` if the string cannot possibly match the pattern even with more characters to read.

    - #### startingWith

          public static JsonTokenType startingWith​(char c)

      Find which JSON value might be starting with a given character
      Parameters:
        `c` - the character
      Returns:
        the possible token type found

    - #### getLabel

          public String getLabel()

    - #### getValidator

          public Object getValidator()
